Sources of Nest Failure in Mississippi Sandhill Cranes, Grus canadensis pulla: Nest Survival Modeling and Predator Occupancy
… flooding, abandonment, and egg inviability. Mean daily survival rate (DSR) was 0.72. The best approximating models included covariates for season date, temperature and nest age. DSR decreased with increasing season date, increasing nest age, and decreasing temperature. Hypotheses related to …

Reproductive Ecology of Long-billed Curlews Breeding in Grazed Landscapes of Western South Dakota
… study were to estimate nesting success and brood survival and to characterize nesting and brood-rearing habitats of a population of long-billed curlews breeding in western South Dakota. This study was conducted during the spring and summer of 2005 and 2006 on the Triple U Buffalo Ranch in Stanley …

Conserving a charismatic grassland species in Illinois: the barn owl
… sites, determine factors correlated with nest survival, and test playback surveys as a method of detection. To this end, I checked all known nest boxes in Illinois and monitored active nests until they fledged or failed. I then compared land cover at occupied and unoccupied nest boxes. To …

Development of Sustainable Harvest Strategies for Cellulose-Based Biofuels: Harvest Effects on Game Bird Production
… was not affected by harvest intensity. Nest survival modeling indicated that survival held constant throughout the nesting period in addition to the additive effect of visual obstruction at the nest (β = -0.013; SE = 0.005) had a negative effect on daily survival rate. Logistic regression …

Piping Plover (Charadrius melodus) habitat selection, survival, and migration on New York barrier islands following natural and engineered habitat changes
… and after Hurricane Sandy and to investigate survival and migration of fledgling piping plovers within their first year. We studied piping plover nest-site selection, habitat, and abundance before (2010) and after (2015) Hurricane Sandy and engineered response. Before the storm, piping plovers …

Habitat selection and breeding ecology of grassland birds in areas managed with fire and grazing
… not responding to management. Cattle stocking rates were adjusted in 2010 in hopes of increasing management efficacy. My research utilized data collected between 2010-2013, and was focused on two broad questions: 1) can management adjustments, specifically to stocking rates, improve the …

Population Dynamics of Piping Plovers (Charadrius melodus) on the Missouri River
… the factors affecting adult and juvenile survival. We used a logistic-exposure model to calculate nest survival. Adult and juvenile survival was calculated using Cormack-Jolly-Seber based models in Program MARK. We used the estimates from these studies to create a matrix population model …
